Answer 1

• DNA:

1. It is the genetic material of the majority of the organisms.
2. It is double-stranded.
3. Deoxyribose sugar is present.
4. Nitrogen bases like Adenine, Guanine, Cytosine, Thymine are present.
5. Specific base pairing is observed.
6. Total number of purines is equal to the total number of pyrimidine. Thus, the purine to pyrimidine ratio is 1:1.
7. It is present in the nucleus. 
8. It is responsible for determining hereditary characters and for formation of RNA.

• RNA:

1. It is a genetic material only of some viruses.
2. It is single-stranded.
3. Ribose sugar is present.
4. Nitrogen bases like Adenine, Guanine, Cytosine, Uracil are present.
5. Nitrogen bases do not form pairs.
6. The amount of purine and pyrimidine may or may not be equal.
